This 115-page report documents how some employers confiscated migrant workers' passports, failed to provide them with written contracts, did not pay regular wages, cheated them of earnings, and required them to work excessively long hours. Human Rights Watch also documented frequent use of child labor, with children as young as 10 working, even though tobacco farming is especially hazardous for children. The report was based on interviews in 2009 with 68 people who were working on tobacco farms in Kazakhstan or who had recently worked there.
